Areas of Interest:

  • My lab focuses on understanding the role of Notch1 in the development and progression of abdominal aortic aneurysm (AAA). Notch1 signaling has recently gained substantial interest because of its potential participation in a diverse array of inflammatory diseases. AAA, defined as a localized dilation of the abdominal aorta, is a life-threatening disease, which has an estimated incidence of 2-4% in the adult population. AAA is characterized by activation of the inflammatory response causing extensive remodeling of the aortic wall. To understand the role of Notch1 in AAA, our laboratory has generated various knockout mice and has reported that loss of Notch1 interferes with the development of AAA at the initial stages by preventing the recruitment of inflammatory cells. Our long term goal is to determine if pharmacologic inhibition of Notch signaling is a viable therapeutic strategy to modulate AAA.
